Muscovite is made up of tetrahedron and octahedron atoms.
Color-white, yellow, silver, green, or brown
Hardness- 2-2.5
Luster- Vitreous
Group- micas
Streak- White
Density- 2.77-2.88
Crystal Structure- Monoclinic
Specific Gravity- 2.8
Cleavage/Fracture- Perfect in one direction producing thin sheets or flakes.
Special Characteristics- The cleavage sheets of muscovite are elastic, which means you can bend them anyway and it will go back to its original shape.
Occurrences- Brazil, CIS, Pakistan, India, Russia, and the United States
Uses- Window glass, circuit boards, ovens, furnaces, and it is used to insulate windows and doors.
Occurrences in Iowa- Adams County, Chippewa County, Dodge County, Clarke County, Eau COunty, Florence County, Forrest County, Iowa County, Juneau County, Marathon City, Marinette City, Rusk City, Sauk County, Waupaca County, and Wood County.
